Short-Term Rental Owners Beware
New Federal Tax Rules Can Strip Your Expense Deductions for Non-Compliance
Short-term rental properties have become a significant part of Canada’s housing and tourism landscape. From downtown condos listed on Airbnb to secondary suites in suburban neighbourhoods, many property owners treat short-term rentals as active business operations.
But as of January 1, 2024, the tax landscape has changed in a meaningful way.
Under new amendments to the Income Tax Act (Canada), landlords operating short-term rentals who fail to comply with provincial or municipal regulations risk losing otherwise deductible expenses — sometimes indefinitely.
This is no longer just about municipal fines or licensing issues. It is now a federal tax exposure.
If you operate, or are considering operating, a short-term rental in Canada, understanding these new rules is critical.
Short-Term Rentals: More Than Just a Side Hustle
Short-term rental operations are subject to layered regulation. Depending on the municipality and province, landlords may be required to:
Register the property
Obtain a municipal business licence
Secure a short-term rental permit
Pay accommodation or tourism levies
Restrict rentals to a principal residence
Comply with safety and occupancy standards
Municipalities such as Calgary, Vancouver, and Toronto have expanded oversight in recent years, introducing licensing frameworks and enforcement mechanisms.
Historically, non-compliance primarily triggered local penalties — fines, revocation of permits, or forced closure.
Now, federal tax consequences have been added to the mix.
The New Deduction Denial Rule Explained
The federal government introduced new rules under section 67.7 of the Income Tax Act targeting short-term rental operators who do not comply with provincial or municipal requirements.
The core concept is straightforward:
If your short-term rental is operating in violation of applicable provincial or municipal laws, you may lose the ability to deduct certain operating expenses for tax purposes.
What Is a “Short-Term Rental” Under the Act?
For these purposes, a short-term rental generally means a residential property that is rented (or offered for rent) for periods of less than 90 consecutive days.
If you rent for 90 days or longer under a single agreement, the property may fall outside this definition.
What Expenses Are at Risk?
Ordinarily, landlords can deduct common operating expenses such as:
Mortgage interest
Property insurance
Utilities
Cleaning and maintenance costs
Platform service fees (e.g., Airbnb or similar)
Property management fees
Under the new rule, a portion of these deductions may be denied if the property is non-compliant during part or all of the taxation year.
How the Denial Is Calculated
The deduction denial applies proportionally.
The formula considers:
The number of days in the year the property was non-compliant
Divided by the number of days it was operated as a short-term rental
Multiplied by the relevant expense
Example 1:
If a landlord incurs $1,000 in deductible expenses and the property was non-compliant for 50 days in a year where it operated as a short-term rental for all 365 days:
$1,000 × (50 ÷ 365) = approximately $137 denied.
Example 2:
If the property operated as a short-term rental for only 200 days in the year and was non-compliant for 50 of those days:
$1,000 × (50 ÷ 200) = $250 denied.
The shorter the operational window, the greater the proportional impact.
For landlords with substantial carrying costs, this can add up quickly.
What Triggers the Denial?
The deduction denial applies where:
Short-term rentals are outright prohibited in that province or municipality; or
Registration, licensing, or permit requirements exist and have not been satisfied.
Importantly, this rule focuses on non-compliance with provincial or municipal laws.
It does not appear to extend to:
Condominium bylaws prohibiting short-term rentals
Federal legislation unrelated to local operating authority
However, landlords must be cautious. Municipal enforcement activity is increasing, and documentation matters.
No Limitation Period for CRA Reassessment
One of the most significant — and concerning — aspects of the new rules is enforcement.
Under normal circumstances, the Canada Revenue Agency (CRA) is limited to a three-year reassessment window for individuals and Canadian-controlled private corporations (subject to certain exceptions).
However, the new provision allows CRA to reassess and deny expenses related to non-compliant short-term rentals at any time.
There is no statutory limitation period specific to this deduction denial rule.
That means:
The CRA may reassess prior years indefinitely.
Interest can accumulate over time.
Penalties may be imposed.
This significantly increases long-term risk exposure for non-compliant operators.
Increased Enforcement Funding
The federal government has also signaled stronger enforcement intentions.
In December 2024, the Department of Finance announced a Short-Term Rental Enforcement Fund, designed to support municipalities in enforcing short-term rental regulations.
This suggests:
Greater municipal scrutiny
Enhanced data sharing
Increased likelihood of audit exposure
Operators should expect heightened coordination between municipalities and federal authorities.
Transitional Relief
The new rules apply starting with the 2024 taxation year.
Limited transitional relief was introduced for 2024 in certain situations, particularly where non-compliance arose due to newly introduced municipal restrictions and operators were actively working toward compliance.
However, this relief is narrow and should not be relied upon without professional advice.
Strategic Options for Landlords
For operators navigating this environment, several strategic considerations arise.
1. Ensure Full Compliance
The most straightforward approach is strict compliance:
Confirm licensing requirements
Maintain up-to-date permits
Document approvals
Retain proof of compliance
Administrative oversight is no longer merely a regulatory issue — it has direct tax consequences.
2. Consider 90-Day Rental Structures
Because the rule applies to rentals under 90 consecutive days, landlords may consider offering longer-term agreements (90 days or more).
This removes the property from the definition of “short-term rental” under the Income Tax Act.
However, changing rental duration may trigger other consequences, including:
GST/HST implications
“Change of use” rules under the Excise Tax Act
Potential impact on municipal classification
Careful tax planning is required before restructuring.
3. Expense Structuring
In some circumstances, landlords may consider structuring certain services (such as cleaning) so that the tenant pays the service provider directly.
If the landlord never receives the income, there may be no corresponding deduction required.
However, such arrangements must be structured properly and evaluated on a case-by-case basis. Improper implementation can create new tax exposure rather than eliminate risk.
Professional tax advice is essential before attempting this strategy.
Broader Market Implications
These changes may influence the short-term rental market in several ways:
Increased compliance costs
Reduced profitability for marginal operators
Greater consolidation among professional operators
Shift toward mid-term rentals (90+ days)
Reassessment of investor strategies
For municipalities already grappling with housing supply pressures, these tax measures may further discourage non-compliant short-term operations.
The Bigger Message from Government
The message from federal and municipal governments is clear:
Short-term rental operations are businesses.
They must comply with local regulations.
Failure to comply will carry consequences beyond municipal fines.
The integration of tax enforcement into local compliance reflects a broader policy objective: tightening oversight of short-term rental markets.
Final Thoughts
For landlords operating short-term rentals, the risk environment has changed.
Non-compliance with provincial or municipal laws may now result in:
Denial of otherwise legitimate business expense deductions
Open-ended CRA reassessment exposure
Accruing interest and penalties
Increased municipal enforcement scrutiny
What once may have been viewed as an administrative oversight can now become a long-term tax liability.
Operators should:
Review their compliance status immediately
Confirm all licensing and permit requirements are satisfied
Maintain detailed documentation
Seek professional tax guidance where uncertainty exists
Each property, municipality, and fact pattern is unique.
In today’s regulatory environment, proactive compliance is not optional — it is essential.
If you are concerned about how these new rules may affect your short-term rental property, obtaining tailored tax advice is strongly recommended before filing returns or restructuring your rental operations.
